I dont understand wanting Galaxy 3. At all. 1 + 2 are amazing and huge. 3 would have been a gigantic waste of Nintendo's time.
If you want to play Galaxy, boot up the two last games in the 3D Mario series.
On the topic of controls, Land was great. Any problems with it were not the design, but the analog circle pad being a lil wonky.
I don't get why people want galaxy 3 either. I'd take an HD release of the first two galaxy games but that is about it.
I just don't like this direction. Not that I don't like this game coming out, but i think i would've been nice if it came out alongside a more traditional 3D mario, rather than it's replacement
